Security researchers note that adware has been a growing threat to Mac users. According to experts' reports, Mac malware is now outpacing Windows infection rate,, and one of the major portions of the infections belongs to adware. While DataQuest can be considered as ad-supported software, its distribution and operation methods are much closer to those of malware.
The principle of DataQuest virus activity is very primitive – it is concentrating on delivering users ads, such as pop-ups, deals, offers, banners, in-text links, coupons, and other commercial content. While in some cases, these ads might be marked by an app or a service it is being delivered from, it is highly unlikely to see “Ads by DataQuest” or “Powered by DataQuest” or similar indicators.
When DataQuest is trying to display ads, it will attempt to connect to unknown domains in the background. This way, the pop-ups, and other ads can be called up when users are browsing the web.

- The homepage, new tab address, and the search engine are set to something else;
- Browser redirects bring to scam, phishing, spoofing, fake update, and similar dangerous websites;
- Some websites might fail to load.
Besides these relatively obvious symptoms, there is a lot that the DataQuest adware can do in the background. One of the main activities that should be concerning is data gathering. Considering that the malware gains elevated permissions on the system, some of the browser extensions might be set to gather all the information you type into your web browser. Besides, adware also usually collects non-personally identifiable information as well, including the IP address, ISP, links clicked, sites visited, search queries, technical details, installed apps, etc.
DataQuest might insert intrusive advertisements on all visited websites and change web browser settings without permission
You should remove DataQuest from your machine as soon as possible, as its deceptive operation might lead to multiple severe consequences, including monetary loss, privacy issues, or even identity fraud. Keep in mind that the app might also be a sign that other threats are already present on the machine, including the notorious Shlayer Trojan.
Ways to recognize fake updates and other tips on how to avoid adware and malware on Macs
For many years, Mac power users and even IT experts claimed that Mac malware does not exist, and there is no need to employ any third-party security tools in order to protect it. According to them, the built-in defenses like GateKeeper and XProtect are more than enough – and they would be correct several years ago. Most of Mac malware nowadays utilize various techniques to bypass these defenses, such as using fake digital signatures that would circumvent GateKeeper's functionality. Additionally, users can always grant permission for malicious files to make changes to the system once they are tricked by a sophisticated phishing alert online.
Thus, it is important to know how Mac malware spreads in order to avoid it in the future. Two main methods are used by cybercriminals:
- Fake Flash updates. This technique is well-known to cybersecurity experts and many regular users, as it has been employed for years. Flash is a plugin that allowed multimedia to be delivered to users from various sites, and they would often see the “Flash required” prompts everywhere. While the technology was long replaced by HTML 5 in 2014, and practically all websites got rid of the flawed Flash Player. Nevertheless, because the plugin is so embedded in users' memories, they still believe that they need it. All in all: do not ever click on Flash update prompts on various sites, as they are fake, and you do not need the plugin as a regular user in the first place.
- Software bundles. Apple Store currently holds more than 1.8 million applications, so there is a good reason to limit downloads from there. Nevertheless, third-party sites often host installers that compile multiple programs – these are often deliberately hidden using various techniques, such as pre-ticked boxes, misleading deals, etc. Thus, always pick Advanced/Custom settings instead of Recommended/Quick ones and get rid of ticks that would otherwise allow the installation of media players, extensions, and other unwanted programs.
In most cases, users get infected with DataQuest malware after they get tricked by fake Flash Player update
